Inventor: SAWARA KUNIZOU
IPC: H01L21/60
Filed: 1982-07-30
Abstract: PURPOSE:To obtain low resistance and inexpensive fine wirings by forming by a thin film technique inner leads in a multilayer structure, and laminating a high bonding material with ceramic, conductive material and preferably contacting material with the wirings. CONSTITUTION:Inner leads 4 are laminted on a ceramic base 1 in the sequence of aluminum 11, Cu 12 and aluminum 13 from the lower layer. Rigid leads are formed without exfoliation by the high adhesive between the aluminum 11 and the ceramic 1, the aluminum 13 of upper layer improves the supersonic bonding with the aluminum wirings 5 to rigidly connect therebetween, the Cu 12 at the intermediate lowers the entire electric resistance. In manufacturing, a thin film forming method such as photocomposing method can be used. Accordingly, fine wiring pattern can be formed, coupled without Au plating, thereby reducing the cost of a semiconductor device.

Title: Fuel injection valve
Inventor: TAKAISHI TATSUO
IPC: F02M61/10
Filed: 1981-08-25
Abstract: PURPOSE:To reduce combustion noise and smoke and improve fuel efficiency, by providing a ramified oil passage which communicates to an oil reservoir of an injection valve and has a piston and a check valve and is located in parallel with a needle valve and by keeping the ratio of injection low in its initial stage and by preventing injection at low pressure and a low ratio in the rear stage after main injection. CONSTITUTION:High-pressure fuel flows to an oil reservoir 101 through an oil passage 2 and to another oil reservoir 111 through an annular oil passage 112. When the pressure of the reservoir 101 is at a valve opening level Po, that of the other reservoir 111 is at the same level  and a piston 13 is moved up nearly simultaneously with a needle valve 3. For that reason, the  increase in volume at the time of the ascent of the needle valve 3 is the sum of the increases in the volumes of the reservoirs 101, 111, so that the increase in volume at the time of the ascent of the needle valve is large. Fuel is injected by the ascent of the needle valve 3 and ignited and burned. After the discharge of the fuel, the needle valve 3 is seated, a check valve 10 is closed at the side of the piston 13 and the flow rate of fuel is reduced by an orifice 12 so that the fall in the pressure of the oil reservoir 111 becomes slow. The pressure of the reservoir 111 is made lower than the valve opening level Po so that the piston 13 is moved down after the needle valve 3 is seated. For that reason, fuel corresponding to the change in volume at the time of the descent of the piston 13 is not injected from an injection port 8, so that injection stoppage after main injection is made sharp.

Inventor: OZEKI TADASHI
IPC: F01C21/18
Filed: 1994-06-15
Abstract: PURPOSE:To reduce the size of the whole of a system and improve recovery of energy by a method wherein pressure liquid delivered from two gear mechanisms for driving a pump is joined and fed to the actuator side and pressure liquid fed from the actuator side to the gear mechanisms is fed to only one gear mechanism by a check valve.

IPC: B24B49/14
Filed: 1987-05-28
Abstract: PURPOSE:To avoid the need of a large-sized motor for a grindstone and improve the working efficiency and suppress the thermal trouble such as grinding burn providing an allowable range for the grinding resistance of a rotary grindstone for grinding the burrs of a work and controlling the approach speed between the work and the rotary grindstone. CONSTITUTION:Grinding is started after inputting the data such as the locus for grinding a work 18, upper and inermediate set values of the grinding resistance, and the advance speed of a rotary grindsrone 10, and a control panel 28 always measures the grinding resistance of the rotary grindstone 10 as the electric currnent value of a driving motot 12. The grinding resistance and the upper and intermediate set values are compared, and if the grinding resistance is less than the intermediate set value, grinding is performed as set in the initial time, and when the grinding resistance is over the intermediate set value and less than the upper set value, the advance speed of the rotary grindstone 10 is decelerated to the set value, and when the grinding resistance exceeds the upper limit value, the rotary gringstone 10 is once separated from the work 18, and then advance grinding is perfornmed at the initial speed again. Therefore, the grindstone 10 does not apply a pressure over a certain value onto the work 18, and the need of a large-sized motor is avoided, and grinding is not interrupted, and the working efficiency can be improved, and the thermal trouble such as grinding burn of the work can be prevented.
